there was a how to rebuild a 16g to but i think you need to visit my Cardomain site for that now

 

Awesome thanks guys...I will read up on it

 

I ended up buying a rebuild kit and it should be here sometime this weekend or early next week. Also I purchased a flange for the outlet becuase I want a custom DP to eliminate the slight leak I have from the EGR, plus its a waste to have the long stem coming out of my existing DP going to nowhere. How much would you pay to have a normaly exhaust shop fab up a 2.5 inch downpipe all the way to the Cat? I am thinking along the lines of 100 dollars does that sound about right? Also does anyone know where I can find a 2 bar MAP sesnor, I still cannot use my WI yet.

 

$100 is on the cheap side. $200 is more like it. I bet my local guy would do $100 though. So you might make out easy.

 

Yah its awesome when you have a guy . I have a little shop right around the corner, they welded my EGR pretty nicely for only 5 dollars...Good people

 

Update:
Just got a great new t25 "nissan one IIRC it has the 3 bolt compressor outlet". I hooked everything up yesterday and what a difference. I took it out for a ride, but on the way out I noticed a oil leak from the feed inlet side. So since I was in the street I drove it approximately 1,000 feet and only felt 2 pis of boost. What a difference a working turbo makes, it actually felt better then my old one @ 6 psi. Anyways I made a U-turn and came back home "I was only out for approximately 20 seconds". I wasn't able to fix the leak because it was 11:30pm so I just left the car @ home and carpooled today. I will have updates regarding the performance later after I fix the leak. Also I am going to save up for MS now and start using my WI utilizing the MS 2.5 map. Thanks for all the help.

 

why are you quoting yourself?

 

sorry just trying to explain what is going on with the build...
:fm: LOL @ this smiley

 

I got everything working yesterday, but I only seem to be hitting 3.5-4 psi around 5K. I don't think the gauge is loose or anything. I have the wastegate tight and I sprayed all my chargepiping with Brake cleaner, but found no leaks. Could there be something else contributing to low boost? After driving the car for approximately 10 minutes my idle drops a bit when I come to a stop but then rises again, is this due to running rich? Thanks everyone.

 

Got everything running good, boost (only 4.5-5 psi for some reason) is hitting good but I have a few more problems.
My idle is fine during warm-up but when I start hitting boost after approximately 10 minutes of previous driving my idle gets really messed up. Sometimes it drops to approximately 300-500 rpm and will fluctuate...also it can sometimes go as high as 1,600 with fluctuation as well. I am getting a P0172 code "rich, but I can reset that with my scangauge". Lastly I have a slight oil leak from the return line @ the turbo, but I think it could be just a little to close to the manifold, heating up, expanding hte hose and letting small amounts of oil out. I know the oil line problem is just a bad hose or too close to the manifold, but are the other two problems normal? I searched a lot of threads for the idle but did not find any real fixes. I think this is due to my management, but can anyone help? I plan to go with MS as soon as I get the cash. Thanks

 

You have the stock injectors in it now or those other ones? If they're not stock then there is no fix. Where is your IAT sensor located? You're just running the stock ECU right?

 

I am running my stock ECU and injectors...My IAT sensor is located in the my intake piping approximately 6 inches from the compressor wheel...should this be moved into the charge piping?

 

Your iat should be fine there, i wouldn't bother. I ran my car for like 8 months with the IAT just laying in the engine bay. I was running intercooled though.

 

I too am running a FMIC...yah the idle is the only hard part to deal with, the code I can just delete with my scangauge. I think it is probably all management issues and not a bad sensor or anything. I am trying to save up for MS right & a CAS. Also cjernigan you sell a boomslang harness for MS correct? Please PM if so...thanks

 

It's really common for IAC valves to die on 99s, just like it's common for coil packs to die on them. Next time it starts going crazy like that unplug your IAC valve while it's running to see what happens.

 

gotcha,

I think my recirulating BOV into the intake ducting may be an issue...I don't believe it makes a complete seal so some air could be escaping...I will try both today...thanks

 

If your idle is surging like that you likely have a vacuum leak. So a leaking BOV would definitely be a possible cause.

 

is the TT BOV leaking on you too ryan?

 

Shouldn't my stock Audi BOV leak @ idle? I updated teh piping to mandrel bends...it is completely sealed except for the filter of course, but the problem still exist. I think it may be a IAC issue which I will clean today. Do I need a PCV on the breather line to the intake? Thanks

 

You need a PCV installed on the line going from the valve cover to the intake manifold, not on the driver side.
Your BOV might be leaking, listen to see if you can hear it.
